Abstract
An active sitting chair is provided that encourages a sitter/user to sit actively by requiring balance adjustments and core engagement. The active sitting chair can be efficiently produced while being relatively sturdy and lightweight. The main body may be a monocoque shell that includes a rounded lower portion that contacts the surface the chair is on and promotes wobble of the chair when a sitter is seated on the chair. The chair may also include built-in handles for ease of lifting and a seat portion at the top of the chair that may include a cushion or similar component for increasing the stability and/or comfort of a sitter.

- and
- a rounded lower portion attached to the bottom portion and arranged to rest on a supporting surface,
- wherein the first side portion is attached continuously along the first side edge and forms a first inwardly curving uninterrupted surface extending across an entire first side area bounded by the bottom portion, the top portion, the front portion, and the rear portion and the second side portion is attached continuously along the second side edge and forms a second inwardly curving uninterrupted surface extending across an entire second side area bounded by the bottom portion, the top portion, the front portion, and the rear portion such that the first inwardly curving uninterrupted surface, the second inwardly curving uninterrupted surface, the top portion, the bottom portion, the front portion, and the rear portion form a hollow, uninterrupted monocoque shell with no open areas passing through any part of an area surrounded by the ring-shaped outer portion.
